It's all a bit daunting when you first start - the office help is as good as anything.
probably the best way to start is to record the basic (ha ha) moves ... an then modify and tidy the code
http://spreadsheets.about.com/od/advancedexcel /ss/excel_macro.htm
when recording I like to use key presses rather than menu options (although you can't avoid it)
so the process is something on the lines of ....
start a new worksheet
enter =now() in a cell (a1)
fill column b1 - b5 with any old rubbish
start the recorder
put cursor in a1 (click on a1)
ctrl+c (copy)
right arrow (shift cursor 1 column to the right (into b))
Ctrl + down arrow (shifts cursor to last filled cell)
down arrow (moves crsr into the first free cell in col b)
ctrl +V (paste)
left arrow (move cursor one cell left)
ctrl + up arrow (returns cursor to a1 [=now()]
alternatively just click on a1
stop recorder
and that's it
slap a button in there (you can put it under a custom button in the menu) .... and you are set
it's simple and (I hope) logical
you start and end by selecting a1 so that if someone catches a key ... it should still work.
then you can look at the macro and see what does what .... pretty soon you'll want to tickle it up and get rid of any spurious instructions .... then you'll want to put in some error checking and formatting and .... and ....
and then you're lost ... it'll be down to oxfam to buy an anorak ... and you'll get an irresistible urge to become a level 98 magus
then - the saddest of all .... you'll start giving advice on the AB technology thread
